See: Description

Interface Summary

Interface	Description
Activity<ConfigurationType>	Defines a single abstract or concrete invokable activity.
ActivityFactory	Factory for creating Activity instances.
ActivityInputPort	Specialisation of InputPort to capture the extra information required by Activity instances.
ActivityOutputPort	The output port of an Activity.
ActivityPort	The input or output port of an Activity.
AsynchronousActivity<ConfigurationType>	A concrete invokable activity with an asynchronous invocation API and no knowledge of invocation context.
AsynchronousActivityCallback	The callback interface used by instances of AsynchronousActivity to push results and failure messages back to the invocation layer.
LockedNestedDataflow	A LockedNestedDataflow is intended to be unchangeable.
MonitorableAsynchronousActivity<ConfigType>	An extension of AsynchronousActivity with the additional stipulation that implementing classes must return a set of monitorable properties for the activity invocation instance when invoked.
NestedDataflow	Nested workflows/dataflows can come in many shapes and sizes - in-line, url etc.
NestedDataflowSource<T extends NestedDataflow>
SupersededActivity<ConfigurationType>	A superseded activity is one which has been replaced be another activity type of similar functionality but different configuration and name

Class Summary

Class	Description
AbstractActivity<ConfigType>	Convenience abstract superclass for generic Activity instances.
AbstractAsynchronousActivity<ConfigType>	Abstract superclass for asynchronous activities.
ActivityAndBeanWrapper	Used when dragging activities from the palette onto "something".
DisabledActivity	A disabled activity is a wrapper for an Activity that is offline or similarly disabled.
Job	Contains a (possibly partial) job description.
NonExecutableActivity<T>	A non-executable activity is a wrapper for an Activity that cannot be executed, for example because it is offline or unrecognized.
UnrecognizedActivity	An unrecognized activity is an activity that was not recognized when the workflow was opened.

Exception Summary

Exception	Description
ActivityConfigurationException	Thrown when attempting to configure an Activity instance with an invalid configuration.

Package org.apache.taverna.workflowmodel.processor.activity Description

Provides definitions for a single Activity to be contained within a Processor. Activity was previously called 'Service' but this was somewhat misleading as there wasn't always a service backing it. The Activity may be abstract, it may be synchronous or asynchronous in which case it uses a callback mechanism. It doesn't carry around annotation itself instead using an activity annotation container to handle this (this avoids third parties having to manage annotation containment themselves).
